NAME

       function::get_cycles - Processor cycle count

SYNOPSIS

           get_cycles:long()

ARGUMENTS

       None

DESCRIPTION

       This function returns the processor cycle counter value if available, else it returns
       zero. The cycle counter is free running and unsynchronized on each processor. Thus, the
       order of events cannot determined by comparing the results of the get_cycles function on
       different processors.
